POWER WINDOW
With the ignition SW turned on, current flows through the GAUGE fuse to TERMINAL 7 of the integration relay to TERMINAL
(A) 12 to TERMINAL 1 of the POWER relay to TERMINAL 2 to GROUND, this activates the relay and the current flowing to
TERMINAL 5 of the relay from the POWER fuse flows to TERMINAL 3 of the relay to TERMINALS 10 and 11 of the power
window master SW.
1. MANUAL OPERATION (DRIVER'S WINDOW)
With the ignition SW turned on and with the power window master SW (Driver's) pulled to the up side the current flowing from
TERMINALS 10 and 11 of the power window master SW flows to TERMINAL 1 of the master SW to TERMINAL 1 of the
power window motor to TERMINAL 2 to TERMINAL 5 of the master SW to TERMINALS 3 and 4 to GROUND and causes
the power window motor to rotate in the up direction. The window ascends only while the SW is being pushed.
In down operation, the flow of current from TERMINALS 10 and 11 of the power window master SW to TERMINAL 5 of the
master SW causes the flow of current from TERMINAL 2 of the power window motor to TERMINAL 1 to TERMINAL 1 of the
master SW to TERMINALS 3 and 4 to GROUND, flowing in the opposite detection to manual up operation and causing the
motor to rotate in reverse, lowering the window.
2. AUTO DOWN OPERATION (DRIVER'S WINDOW)
When the driver's window SW is pushed strongly to the down side, the current flowing to TERMINALS 10 and 11 of the
power window master SW flows to the down contact point and auto down contact point of the driver's SW.
This activates the relay (Down side) inside the power window master SW and the hold circuit also turns on at the same time,
so the relay (Down side) remains activated even when the SW is released.
Current flows at this time from TERMINALS 10 and 11 of the power window master SW to TERMINAL 5 to TERMINAL 2 of
the power window motor to TERMINAL 1 to TERMINAL 1 of the power window master SW to TERMINALS 3 and 4 to
GROUND, so the motor continues to operate until the driver's window is fully down.
When the driver's window finishes down operation and the hold circuit goes off, so the relay (Down side) also turns off. This
stops the current flowing from TERMINALS 10 and 11 of the power window master SW to TERMINAL 5 is cut off, so the
power window motor stops and auto down operation stops.
When the driver's SW is pulled to the up side during auto down operation, the hold circuit is turned off so the current flowing
from TERMINALS 10 and 11 of the power window master SW to TERMINAL 5 is cut off and the power window motor stops.
If the SW remains pulled up the relay (Up side) is activated, so current flows from TERMINALS 10 and 11 of the power
window master SW to TERMINAL 1 to TERMINAL 1 of the power window motor to TERMINAL 2 to TERMINAL 5 to
TERMINALS 3 and 4 to GROUND, the power window motor rotates in the up direction and manual up operation occurs
while the SW is pulled up.
3. MANUAL OPERATION (FRONT RH WINDOW)
With the power window control SW front RH pulled to the up side, the current flowing from TERMINAL 4 of the power window
control SW flows to TERMINAL 3 of the power window control SW to TERMINAL 2 of the power window motor to TERMINAL
1 to TERMINAL 1 of the power window control SW to TERMINAL 2 to TERMINAL 6 of the master SW to TERMINALS 3 and
4 to GROUND and causes the power window motor front RH to rotate in the up direction. The up operation continues only
while the power window control SW is pulled to the up side. When the window descends, the current flowing to the motor
flows in the opposite direction, from TERMINAL 1 to TERMINAL 2, and the motor rotates in reverse. When the window lock
SW is pushed to the lock side, the ground circuit to the front RH window becomes open.
As a result, even if Open/Close operation of the front RH window is tried, the current from TERMINALS 3 and 4 of the power
window master SW is not grounded and the motor does not rotate, so the front RH window can not be operated and window
lock occurs.
4. MANUAL OPERATION (REAR LH, RH WINDOW)
With the power window control SW rear LH, RH pulled to the up side, the current flowing from TERMINAL 3 of the power
window control SW flows to TERMINAL 1 of the power control SW to TERMINAL 2 of the power window motor to TERMINAL
1 to TERMINAL 5 of the power window control SW to TERMINAL 4 to TERMINAL 12 or 13 of the master SW to TERMINALS
3 and 4 to GROUND and causes the power window motor rear LH, RH to rotate in the up direction. The up operation
continues only while the power window control SW is pulled to the up side. When the window descends, the current flowing
to the motor flows in the opposite direction, from TERMINAL 1 to TERMINAL 2, and the motor rotates in reverse. When the
window lock SW is pushed to the lock side, the ground circuit to the rear LH, RH window becomes open.
As a result, even if Open/Close operation of the rear LH, RH window is tried, the current from TERMINALS 3 and 4 of the
power window master SW is not grounded and the motor does not rotate, so the rear LH, RH window can not be operated
and window lock occurs.
SYSTEM OUTLINE

5. KEY OFF POWER WINDOW OPERATION
With the ignition SW turned from on to off, the integration relay operates and current flows from the DOOR fuse to
TERMINAL (A) 13 of the relay to TERMINAL (A) 12 to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND for
about 43 seconds. The same as normal operation, the current flows from the POWER fuse to TERMINAL 5 of the power
relay to TERMINAL 3 to TERMINALS 10 and 11 of the power window master SW and TERMINAL 4 (Front RH) or 3 (Rear
LH, RH) of the power window control SW. As a result, for about 43 seconds after the ignition SW is turned off, the functioning
of this relay makes it possible to raise and lower the power window. Also, by opening the front doors (Door courtesy SW on)
within about 43 seconds after turning the ignition SW to off, a signal is input to TERMINAL 6 or (A) 8 of the integration relay.
As a result, the relay turned off, and up and down movement of the power window stops.

DOOR LOCK CONTROL
Current always flows to TERMINAL (A) 13 of the integration relay through the DOOR fuse.
When the ignition SW is turned on, the current flowing through the GAUGE Fuse flows to TERMINAL 7 of the integration
relay to TERMINAL (A) 12 to the POWER relay (Coil side) to GROUND.
1. MANUAL LOCK OPERATION
When the door lock control SW or door key lock and unlock SW are operated to LOCK position, a lock signal is input to
TERMINAL (A) 1 or (A) 3 of the integration relay and causes the relay to function. Current flows from TERMINAL (A) 13 of
the relay to TERMINAL (A) 6 to TERMINAL 2 of the door lock motors to TERMINAL 3 to TERMINAL (A) 7 of the relay to
TERMINAL 10 to GROUND and the door lock motor causes the door to lock.
2. MANUAL UNLOCK OPERATION
When the door lock control SW or door key lock and unlock SW are operated to UNLOCK position, an unlock signal is input
to TERMINAL (A) 2, (A) 4 or (A) 5 of the integration relay and causes the relay to function. Current flows from TERMINAL (A)
13 of the relay to TERMINAL (A) 7 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL (A) 6 of the relay
to TERMINAL 10 to GROUND and door lock motors causes door to unlock.
3. DOUBLE OPERATION UNLOCK OPERATION
When the door key lock and unlock SW front LH is turned to the unlock side, only the driver's door to unlock. Turning the
door key lock and unlock SW front LH to the unlock side causes a signal to be input to TERMINAL (A) 4 of the relay, and if
the signal is input again within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL (A) 7 of
the integration relay to TERMINAL 3 of the door lock motors to TERMINAL 2 of the door lock motors to TERMINAL (A) 6 of
the relay to TERMINAL 10 to GROUND, causing the door lock motors to operate and unlock the doors.
4. IGNITION KEY REMINDER OPERATION
When the door is locked using the door lock knob with the ignition key remaining in the key cylinder and door opened, it is
automatically unlocked. Additionally, if lock operation is made by the door lock control SW or door key lock and unlock, after
the lock operation is completed, the doors are unlocked automatically.
